A method of graph element extension through visual interface

Abstract

The invention discloses a method for extending a pixel by means of a visual interface. The method mainly comprises the steps that a user defines the pixel to be extended in the interface; whether the pixel is included in a configuration file or not is looked up, if yes, it is prompted that the pixel is repeated, and if not, the pixel is defined in the configuration file, that is to say, the pixel is registered in the configuration file; the interface is automatically refreshed, and a newly-increased pixel is displayed; the user draws a picture by means of the newly-increased pixel; the newly-increased pixel is saved in an element model; the model is saved, and the extended pixel and attributes thereof are saved in a json file; when the json file is converted into a background model, the extended pixel generates a corresponding background model; when exporting is conducted, the extended pixel generates a corresponding xml. Therefore, the defects that in the prior art, when the pixel is extended, the model complexity is too high, the user using difficulty is high, and the usability is poor can be overcome.

Description

technical field [0001] The invention relates to the technical field of graph element extension, in particular to a method for extending graph elements through a visual interface. Background technique [0002] Primitive extension can be applied to various modeling tools. As long as a set of primitives needs to be provided to the user in the modeling tool, it is generally necessary to extend the primitives to meet the needs of different users. For example, in the process designer, it is necessary to provide users with a graph element extension mechanism so that users can configure additional graph elements they need. [0003] In order to provide users with an extensible mechanism, in the past implementation, the following methods are mainly used: [0004] Redundant graphic element method, reserve several graphic elements for users to use, this method is simple to implement, but the scalability is not good, and it may still not meet user needs; [0005] Configuration file met...

AI Technical Summary

Problems solved by technology

[0011] 1. By adding redundant primitives, but this implementation increases the complexity of the model, especially if some users need to expand a lot of primitives, it is necessary to add a lot of redundant primitives, which increases the model The complexity increases the difficulty for users to use, and causes trouble for users who do not need to expand too many primitives

[0012] 2. The developer defines the configuration file. When the user needs to expand, he needs to configure the graphic elements in the configuration file according to a certain format. This method has good scalability, but writing the configuration file has certain requirements for the user, and it brings a lot of trouble to the user. Inconvenient and poor usability
